Trim tab Control Horns

These go on the ends of the Trim Tabs.

Cleaned up and deburred the control horns. Time for countersinking the holes.

Countersunk the rivet holes in the control horns. Looks like the depth of the microstop countersink cage is set just right.

Checked the depth of the countersink. I did a test fit with a loose rivet to make sure that the head was flat across the surface.

Riveted the Control Horns on. I used a old paint roller inside the trim tab skins to hold it open so I could get to the rivets with my squeezer.

Pop Riveted the Spar inside the trim tab skins. Getting closer...

Cutting the trim tab hinges to size. This part was a little confusing, but I figured it out.

Placed the drill guide over the hinges. The drill guide is a heavy duty guide to put the holes in the right places for the pop-rivets.

Drilled all the holes in the hinge. I put blue tape over the holes that shouldn't be drilled.

Ready to close things up. This is where everything gets riveted together.

Done! Looking good!
